IMPROVEMENT IN MACHINES FORWINDlNG SEWING-THREAD UPONSPOOLS.

Specification forming part of Letters Patent No. 5h90?,l dated January' 2, 1866; antedated March 28, 1865.

" Patentedin England January 22, 1859.

Toall whom t may concern: l

Be it known that I, WILLIAM \VEILD, of the city of Manchester, in the county of Lancaster, in the United Kingdomof Great Britain and Ireland, have in vented new aud useful Im provements in Machinery for Winding Yarn or Thread onto Bobbins, Spools', 'or Similar Surfaces; and I-do hereby declarethe following to be afull, clear, and exact description of the same, reference'being had to the accompanying vesheets of drawings, which form a part ot' this specification, and to the letters ot' refer` ence marked thereon.

My invention relates to the machinery for Winding sewing-thread principally upon bobbins or spools for the market; and theobject 'of my improvements is to perform vthis operation wholly or partly by self-acting machinery which shall take the empty spools or bobbius,

wind the thread upon them,stop when the required quantity is Wound upon the spool, cut

an incision in the edge of each spool, tix the end `of the thread therein, sever the thread and discharge theiilled spools, take fresh empty spools,

and start the machine to Wind the thread upon them,l these operations going on continuously as long as motion is given to the machine, provided itis supplied with thread and empty bo b bins or spools.

'Ihe machine forming the subject of this specification is the result of a combination, in a modified and improved form, of two machines described in the specification of a patent grantj ed to me for Great Britain and Ireland, numbered 122, and dated the 22d of January, in the -year of our Lord 1858 5 and in its combined,

mditied, and improved form it is described in the speciijcation of 'a patent granted to me for Great Britain and Ireland, numbered 699,'and .dated the 16th day of March, in the year ot our Lord 1860. Some further improvements in detail made since the date of the last-named patent will he described, but no claim made'herein for such improvements.

In order to enable others skilled iu the art to make and use my invention, I Will now proceed to describe the construction and operation of my improved machine.

The same letters and figures of reference will be used for the same and for corresponding partsthroughout thedraivings.

Figs. 1 and 2 show the framingA ofthe machine With the brackets orvr stands A', carrying the spindle vby which rotating motion is given to the bobbin or spool acted upon by each head. The machine is driven by a belt Working upon the pulley a upon the end ot' a shaft, a', passing from end to end of the machine. The machine is stopped and started by a'belt-guide, a2., upon the end of the vertical shaft a3, carried in'bearings attached to the framing, and at the lower end of this shaft an arm, a, is secured, which is jointed with a rod, a5, passing in front of the machine, the end ot' this rod passing throu'grh a slot in one of" the brackets A2 carrying the box or trough Z, which receives the spools lled with thread, and the end of the rod a5 is made of the form shown, so as not to move too easily bythe working of the driving-belt againstthebelt-guidea. By means of this rod a5 the machine can be conveniently stopped or started from any position in front of it. Motion is conveyed from the first-motion shaft a', by a belt workin g upon the pulley a6, to a series of three pulleys, I) c d, uponI the shaft b', having bearings in t-he headstock part ot' the machine. This belt working upon the three pulleys is in one position when the machine is winding and in another position when the machine is chan,g 1;in.,r the spools, and the guide e for traversing the belt is fixed upon the end of a rod, c', sliding endwise in bearings in the head-stock. The position ot' this rod e is shown by Figs. 1, 5, 6, and 7. It receives end movements from a cam, c2, on the belt-changing cam-shaft e3, this cam e2 acting upon a pin fixed in or formed upon a lever, c4, having its fulcrum on astud, c5, in a bracket or projection from the framing', and the end of the lever e4 has a slot in it lengthwise of the lever, in which slot a pin tits formed upon a collar, e, adjustable upon the sliding rode.

Fig. 8 shows the arrangement ot' the three pulleys on the shaft b. The outside pulley, b,is fast upon the shaft. The middle pulley, c, is loose upon the shaft and has a long boss. The inside pulley, d, is loose upon the long` boss ot' the middle pulley, c. Upon the end of the boss of the middle pulley, c, a spurwheel, c', is secured, which gears with one, c2, upon the friction-pulley shaft c3. These spurwheels are shown in Fig. 7, `and also by red pitch-lines in Fig. 5. l

To the boss or side of the wheel c2 a pulley',

c, is fixed or formed, covered wit-h leather, and.

this pulley works in close contact with a pulley, e7, on the belt-changing.,r cam-shaft e3., so that When permitted the leather-covered friction-pulley gives rapid movement to the pulley-e7., and consequently to the belt-changing cam-shaft e3, which makes two semi-rotations for each set of spools filled with thread, and becomes stationary after each semi-rotation, those parts of the periphery of the pulley e7 opposite the pulley c4 at the end of each movement being cut away to enable the friction-pulley to rotate freely without contact. The manner in which the pulley e7 isbroughtinto contactwith the friction pulley will be explained herein after.

The boss of the inside pulley, d, has a spur- 'pinion, d', secured upon it,which. gears with a wheel, d2, secured upon one end of a shaft, d3,

upon the other end of which a pinion, d4, is

secured, .that gears with a spur-Wheel, d5, on the cam. shaft d6, for e'ecting the changes of the spools. These wheels are shown in Fig. 1 and in other figures of the drawings, and

their red pitch-lines are showny in Fig. 5. The cam-shaft d5, parallel to the front of the machine, is geared by bevel-wheels d?, of'equal diameter with a cam-shaft, de", having bearings in the head-stock at a right angle to the first-named cam-shaft. It is upon these shafts thatthe cams are placed which actuate the parts requiring motion when the change of the spools is taking place.

When the inachinekis Winding; the thread onto the spools tlieulriving-belt is working upon t-he outside pulley, b, and partly upon the middle pulley, c, and when the winding is completed the belt is traversed to the inside pulley, d, still remaining partly upon the middle pulley, and by this movement the winding is stopped and the cam-shafts for changing are brought into operation. The drivin g-belt is always upon the middle pulley. c, so that there is always one part ofthe machine in motion, by .which the other parts of the machineI are brought into gear and ont of gear. The rotary motion for winding the thread onto the spools is transmitted from a spur-wheel, b2, fixed upon the shaft b', and this wheel gears, by means of a carrier or intermediate wheel, b3, on a stud in the framing, with a wheel, b4.

,fixed on.a shaft, bf" passinfr from end to end'of the machine, which shaft gives motion to each separate head. The red pitch-lines of these wheels are shown in Fig. 5. Vhen the spool is filled to the required extent with thread the winding motion has to be stopped as suddenly as possible, and this is accomplished by a brake-belt, b", one end ot' which is attached to a projection from the' framing. It then passes round a pulley-surface formed upon the side of the wheel b2, (see Fig. 8,) and its other end is secured by screws for adjustimgf` the 'tight-f ness to a lever, b, centered upon a stud, bn' fixed in the framing. The free end of thisjrever b9 is acted upon by a cam, 0*, on the h'eltchanging cam-shaft c3, and thus the sudden'l semi'rotation of this shaft to traverse the belt from the winding to the spool-changing pul-V ley simultaneously puts the brake on an d stops the winding, this brake being again released y when the belt-changing cam-shaft makes its next semi-rotation. 4

At high speeds the spool-chan gin g cani-shaft d6 and connected parts are carried forward by their momentum after their motion should stop. To prevent this a brake is used which is a lever, d8, having its fulcrum upon a stud, dg, in the framing. One end of the lever has a surface which is brought into contact with the pulley d by asprving, d, secured to the other end of the lever and to a stud in the fraxninff. This lever is actuated by a cam, de, upon the end of the belt-changing cam-shaft c3, which is formed upon the side of a wheel for conveniently turning` the shaft by hand. (See Figs. 7 and l1.) When the spools are being changed vsome of the parts may vget wrong or get in the way by accident. To prevent'damage should this occur at 'any time, the wheel d2 is secured against a washer that comes against a shoul- .upon it.4

der on the shaft d3 by a screw-nut', which be- I comes unscrewed 'oy the rotation ofthe wheel d2 should any obstruction occur.. (See Fig. 6.) The wheel is screwed suticiently tightA to drive the cam-shafts d6 and (15X when there is no more than the usual strain required for elfe'cting the changes of the spools, as is the case when ever t part works correctly.

The thread is distributed in even layers upon the spools by means ota rotatingshatt,f, having a.rightand-lett-handed screw-thread formed This screw-shaft has bearings upon a frame or stand, A3, secured to the head-stock lframe. Itis arranged, as shown best in Fig. 7, with a set-screw,f, and lock-'nut at one end to prevent end-play. This screw-shalt receives a rotary movement from the shaft b5 by means ot' three wheels, f2 f3 f4, the red pitchlines of which'are shown in Fig. 5. Below the screw-shattfa rod,f,5, is placed, which passes' from end to end ot the machine, and is sup-A ported in bearings formed in the brackets A for each'h'ea-d, and is capable ot' sliding' endwise freely, and it is by the movements of this traversing rod fi that the thread is distributed upon the spools. Upon the traverserod, and just under the screw-shaft, a boss, .f", is placed, which is free to oscillate, being se# cured upon the traverse-rod by means ot adjustable collars f7, so that it is without endplay upon the rod. From the boss f6 two arms extend, one arm on one side, the other on the other side, ot' the screw-shaft, and upon each ot these arms is secured a segment ot' a screwnut, f3, corresponding to the screw-thread ot' the'shaft. and by oscillating the boss part f these nuts are brought one into gear and the other out of gear wil h its corresponding screwi thread upon the shaft, and thus a to-and-tro movement is given to the traverse-rod f5. A

projection is made from the boss part f6 in a horizontal direction, and iuclines are formed upon the upper and lower sides of it, upon each ot' which the end ot' a dat spring', fl", acts, which springs are rmly secured to the headsto'ck, as shown in Fig. 7, where one spring, f1, is supposed to be removed. The ends of both springs touch their respective inclines when the traverse-rod is in its central position; but should it move to one side, then the spring upon that side will be forcibly actedupon` but the spring' upon the opposite side will cease to act. Uonsetjuentiywhile the traverse- 1od is moving t'roin the central position in one direction thcspring on that side is beinfbr bent and pressed to one side by its incline, and is thus charged with force, which will cause. the oscillating part to bring one seg-nient ot' the screw-nut out of gear and the others into gear,

and themagain; the force of the spring is per-v mitted to act.

The mechanism for regulating the times of oscillation of the part f6 consists of a bar, g, fitted in a part of the head-stock framing;` so as to slide free in the direction of its length, but free from lateral play, and upon this side. bar a thin plate otl metal is secured, to project be? youd the end ot the bar. This plate g is 4termed the sh-apex, as its edges are tapered, as shown in Fig'. so thata lille drawn across it will be equal in length 'to the shortest traverse or layer to be put upon the. spool at the barrel, while anothcrline drawn lacross 4at another part ot' the shuper will be equal in length to thelmigrest traverse or layer to be put upon the spool, and other lines drawn across the sha-per, between the two, will represent the lengths ot' the traverse or layers intermediate between the spool when empty, and when tilled these gradually increasing` in length.

The projection f fronithe boss is formed into a socket to receive u tail l'part,j`", which is adjustable in ard and outward. This tail part is ot' the shape shown in Figs. 5 and 7, anditcomesoppositetheshape-plateg. When this tail part rests upon thc upper side ot' the shaper one ot' the screw-nutsfu is in gear with the screw-shattj; and when against the underl side (it-the shaper theother nut is in gear with the screw-shaft. Assuming that one of the screw-nuts 78 is in gear, the tail' part fx will traverse till it arrives at the edg'eot' the shaper, whenv that sprng,-f", which has been charged by the movement will cause the part jS tooscillate. The tail partf'X will then be upon the opposite side of thc shaper,and willtraverse back in the opposite direction till it arrives at the other edge ofthe shaper, when it is again reversed lby the other spring, and so on, each spring"alternately reversing the tail part. As long as the shapcror plate g remains station ary the tra-verse will be uniform in length.- Ther-etere, to vary the length ofthe traverse it4 is. only necessary to vary theposition ot' the shaper to a urea-ter or less distance from the tail part, as by this means the tail partjx will have greater or lesser widths ot the shaper to cross het'ore it is reversed. 'lhe movements are given to the shaper by-a cam, g2, fixed ou a shaft, g3, in suitable bearings in the headstock. This cam acts upon a pin, g,'in the slide-bar, and thel pin is pressed against the cam bya spring', g5, secured to the head-stock frame, which spring acts upon a lever, gs, mounted upon a fulcrum at 97, which lever is jointed with the end ot' the slide-bar g. The shat't g3, upon which thc'shaper-cam is fixed, has intermittent rotatorv motion imparted to it, so as to make one revolution for each set ot' spools filled with thread. This is accomplished by the traverse movement by means ot' a stud,f", tixed in theboss partf", which tits into a. slot formed in 'a lever,j", centered at-fL, and this lever has a "stud tixed in it, which tits in a slot in an arm, g", which is centered on the shaper cam-shaft g3. This arm g3 has a pawl jointed upon it, which acts upon a ratchetwheel, secured by screws to a disk, gx, fixed upon the shaper camshaft g3. Uoncentric slots are tormed in the disk part for the screw-bolts, so vthat the ratchet gf can be adjusted in relation to the Shaper-cam in, the direction of rotation. The ratchet-teeth the belt-changing 'cani-shaft.

may be connected directly with the arm g8, as

shown in Fig. 1l. A fine pitched tooth racketwheel, gv, is fixe'd to the Shaper cam-shaft, anda pawl (not shown) is jointed so as to enter its teeth to prevent any accidental backward movement in the cam-shaft. A wheel, T, is fixed upon the front endot' the sha-per eamshaft, so that it may be' turned when required by hand.

' In winding the thread upon the spools the machine .always begins the first layer and ends the last layer ot' tlinead -upon the saine vside of the spool, and at that instant when the last coil of the last layer of thread has been wound upon the-spools the belt-changing cainshaft e3 is brought into gear to stop the winding part of the machine and bring into operation the spool-changing part of the machine. How this is accomplished will be explained by Fig. 5aa detached view. v

The lever 96 is jointed with and partakes of the movements of the shaper slide-bar g, and

upon its side a steel projection is forined,which will eomeiii contact with two similar projections, e, from the side of a disk, e9, fixed upon These projections upon the disk are so arranged that the disk-plate cannot rotate `without the projections coining in contact with that upon the side of the lever 96. 'B .y moving the lever first in one direction and then in theother the pro` jections e3 will pass, and the disk-plate e9-A will make half-a revolution at each oscillation. It will thus be seen that vthe lever gG and disk e9 form an escapement.

In the'disk-plate e9 are two round pins, e", upon which, as they come round, a spring, ev, acts, of the form shown in Fig. 51. This spring is secured at its lower end to the framing, and it passes through a hook in astud, 0T, adjustable in the framing, the slot or hook in this stud limiting the range of its action. When the ecapenient-disk is arrested by the escape-v tlie angle of the end of thespriiig` ment-lever ev has just passed one of the pins c* lin the escapement-disk, and iii this position `the force of the spring acts to push forward the escapeinent-disk in its direction of rotation, and thus, when the escapeinentdisk is released, the spring acts to force the changing cani-shaft e3 round till the pulley e" bites upon the frictionpulley di, and this suddenly rotates the beltvchanging cam-shaft., and the other pin, ex, as it comes around, forces the spring e" back again, and thus recharges it for the next starting movement.

During the time the last layer of thread .is being wound upon the spools the sliaper camshaft g3 is receiving motion and is moving the shaper-bar g, and consequently the end of the,

escapement-lever g, so that the projection upon its side becomes free from that upon the :disk-plate when the last coil is being wound upon the spools. This allows the escapementdisk to makea semi-rotation, which stops the winding and brings the spool-changing cams into operation. The edges of the projections upon the escapemeiit-leyer and plate require very accurate adjustment, so that the stoppage of the winding shall take place attlie exact4 time, and this is effected by mountin g the fulcrui'n of the escapement-lever gi so vas to slide to and fro in a slot, and by arranging an,` adjustingfscrew, gL, to act upon it, as

'fshown in Figm'i. By this means a fine adjustment is obtained, as a small movement of the fulcruin of the escapenieiit-lever is still further divided or reduced, owing to the leverage or ratio between the entire lengthof the lever and the length from vthe jointed end to the projection on the side ofthe lever. The same exactiiess in starting is not so necessary as in stopping the winding, but.- this is accomplished suddenly.'

Upon the end oi the cam-shaft d6* (see Fig. 5) an arm, fly, is fixed, having a slot in it in which a stud is fixed, and upon this stud a rod, (1T, is jointed, which connects it with another stud in an arm, gw, which can oscillate freely upon the end of the shaper cani-shaft. On the arm gw a pawl is jointed, which works upon the edge of a disk, gy, fixed upon the Shaper canishaft'. In this disk there is one ratchet-notch. It will now be seen that when the cam-shaft d.GX for changing the spools begins to rotate the crank-pin dv will cause the arm gw to move and make one oscillation for one revolution of the camshaft. The single ratchet-notch in the disk `gy is in vsuch position when the cam-shaft dsx. begins to move that the pawl will pass over-.the notch in the direction it iiist begins to move, but in its back movement it will enterthe -notch and give movement to the shaper cani-shaft. This will cause the edge of the sliaper-cam g2 to escape from the edge of the square pin g4 in the sliaper slide-bar, at.

which moment the spring g5 will force the escapen'ient-lever g6 back, and this will again release the escapement disk, whenthe beltchaiigin g cam-shaft will stop the motion of the spool-changing cam-shaft and start the winding part of the machine into operation again.

When the machine has filled a set of spools with thread the traverse-rod is left at one extreme of its greatest traverse, and before the winding of the thread upon a fresh set of spools can commence the traverse-rod requires to be adjusted so that the threadguides will come opposite one end of that part of each spool close to its barrel. To accomplish this object a slide-bar, h, is titted'alongside of the Shaper-slide g, so that it can slide endwise when sutiicieiitforce is applied but itispressed upon by a spriii g so as not to move by accident; and this slide-bar h is acted upon by a pin, h', in the side.of the shaperslide-bar, which piu plays iii a gap inA the slide-bar h, this gap beingof such length that the pin h will come in contact with the slide-bar h and carry along with it for, say, the last sixteenth of an' neither ot' the screw-nuts ffl-is in contact with. Consequently the trayerseg the Screw-shaftf. rod f5 can be moved endwise. The traverse'- rod is adjusted by means ot an incline,` h2, corresponding to one side of the Shaper, and this incline rests upon a. projection from the Stand A3, carrying the screw-Shaft j', and the incline actsupon a pin or collar on the trav-A erse-rod f5. rifhis incline h2 is at the end of a rod, h3, adjustablein length by a screw-coupling, and is attached to a stud, h4, fixed in the shaperSlide-bar,asshownin Fig.7. Itwillnow be seen that when the Shaper Slide-bar makes `its quick back movement the traverse -rod vwill be simultaneously adjusted, as the tailpiece fx will be held in the central position to the last moment, when the pin L/in the Shaper `slide-barwill come in contact with the slideb'ar h and move it hack, so that its end releases the tailfpiece f"` and allows one ot' the springs f1 to force oneof the nuts f8 into gear with the screw-thread of the screw-shaftf.

The slide-bar It would be 'necessary if the back movement took place Slowly; but it has now been discovered.l that it maybe dispensed with, as the movements are so rapid that the tail-piece fx has not time-to fall before the adjustment is eftected; but to dispense with the slide-bar h the machine must be arranged so that the tail-piecefx will remain, say, just at the edge, and at the-upper Side ot' the Shaper when lthe `windingis completed, Then by adjusting the incline h2 with a slight play or space the tail-piece will pass freely from the edge ofthe Shaper by the time the adjustment of the traverse-rod has been eli'ected. 1j Thetraversebar f5 is round, and is kept from oscillating by an arm, f, fixed upon it, whielilias a hole in it to slideV upon a Stud ixed in the stand carrying the screw-shaft.

It has already been explained that the shaft b5 gives the rotary motion for winding the thread upon the spools, there being a toothed wheel, bv, upon this shaft for each head of the machine, which wheelgears with a wheel, k, having a hollow axis, It', arranged in bearings ina bracket, A', as shown in Fig. 9.' Within this hollow' Shaft a spindle, L2, is fitted, which isarranged with a key andkeyway, so thatit will rotate with the hollow axis 7c and move -endwise This spindle is connected w'ith an arm, k3, as shown in Fig. 9, in which the spindle can rotate, and this arm is Secured upon one, h4, of three similar rods, kt, l, and m', passing from end to end of the machine, each rod being capable ot'sliding to and fro endwise.

Each of these rods is connectedby a link, 105,

l', and m', to-one arm ofa lever, and the three levers lc, Z2, and m2 for the three rods are centered upon the sume axis k7, and each lever is acted upon by a separate cam, 7:8, Z3, and m3,' one ol which is fixed upon the cam-shaft d5", and the other two are secured by bolts to the tirst, concentric slots bein gformed in the other two cams for the bolts to pass through, so as to allow the cams to be adjusted to their proper relative position to each other upon the e'amshaft.

The parts leg and k* shown in Fig. 9.are

`merely shields or covers.

Upon the front. end ofthe spindle k2 a collar or hoop, kv, is shown in Fig. l), which will slide freely in the lengtlnvay ot' the spindle; but it is carried roundwith the spindle by means ot' a pin which fits into a slot in the collar or hoop. Upon the spindle k2 a spring, kT, is placed, which ,acts against a shoulder upon the spindle and against the hoop 7c",

tending to force it against the spool, that edge ofthe hook coming against. the spool being serrated to take hold of it. When the spindle k2 is withdrawn bythe action ot' the cam k the end oi' the spool comes against a projection, kL, from the bush or bearing of the hollow spindle. (See Fig. 9.)

The spool is 'forced uponthe spindle and kept in its correct position by a hollowspin die, Z4, which is arranged, as shown in Fig. 9,' free to slight end movements in an arm, Z5', secured upon one, l, of the three sliding rods. A Spring,`l"', is secured to the arml5, which presses against the end ot' the hollow spindle l", so that when the cam J has forced the spool tightly against the shoulder upon the spindle 'a slight. hack motion may be given, leaving the springs to 4press the spin'-A dle against the end ot' the spools. y this means provision ismade for slight variations inthe length ot' the spools, and they are thus held by. a uniform pressure. instead ot' one being htight and another slack, as is the. case where there is no similar elastic provision.

The thread to be wound upon the spools is dra-wn in each head from ott'the end ol alarge bobbin, 'f/z, lixed as shown in Fig. 12. lt then passes over a rod, n', then through a wire eye, n, then between two pins or guides, afhthen between pinching-surfaces a4 along the threadguide onto the spool.`v

The thread-guide holder (see Figc. i) and 10) -is formed ol" al hollow boss, n, having two projecting arms. 'lhe hollow boss lits upon the traverserod f5, upon which it is tree to oscillate; but it is prevented from moving endwise by two collars, n6,scciiieil to the traverse-rod, as Shown. One of the projecting arms forms a socket to receive the thread-guide nl, which is formed, as shown, in two parts, the part pressing upon the spool being made ot' steel, and is secured to the other part by a screwbolt, as shown, so that the steel -part may `be readily renewed or changed to suit the thickness ofthe thread, as that edge pressing upon the spool is grooved to correspond with the pitch of the threads when wound upon the spool, so as to give tothe thread the smoothing and polishing e'ect required in the trade. The other arm, a, projecting from the boss a5, has a pin or stud in it, upon which iits the notched end of a rod, p, so that by lifting the rod it may be readily detached from the arm. This rod p is adjustable in length' by a screwvcoupling link, p', and its other end is jointed with an arm, p2, (one for each head,) upon a shaft, p3, passing along the back of the machine from end to end. (See Fig. 12.) To other arms from this shaft p3 chains p4 are attached, which pass over anti-friction pulleys p5 on a shaft, q2, a weight, J6, being suspended at the end ot' each chain. (See Fig. 12.) It is by` means of the shaft p3, arm-p2, and rod p that force is tra-nsmitted to press the threadguide n7 against the spool when winding.

It isthe custom of the-trade to give extra pressure upon the thread-guide in winding by .hand during the last layer to produce a polishing effect. This may be accomplished by connecting au arm, p7, on the shaft p3 with one end of a rod, p8, the other end being jointed with one end of a lever, p, having its fulcrum upon a stud in the framin The other end of this le\ er has a square pin in it, which comes opposite the edge of a projection upon the side ot' the ratchet-wheel gv upon the shaper camshaft g3. (See Fig-:1.5 and 7.) The increase4 of pressure for polishin is edected by causing the pin in the lever p9 to come in contact with the projection at, say, the last layer but two, by which means the use of the thread-guides by each layer is resisted, and consequently there is an increase of pressure. n The threadguide and other parts have sufficient elasticity to give way to a slight extent. ln this case the edge of the square pin in the lever p9 is Vjust free from the edge of the projection when the winding is completed, so as to leave the thread-guides at liberty to be lifted and held up while the spools are being' changed.,

The thread-guides may be lifted by a cam upon the belt-chan gin g cam-shaft c3 but it is now preferred to lift them by one, p", of the set of cams upon the cam-shaft d, which acts upon a lever, 17", centered at r2, and the inotion of this lever is transmitted by a rod, 1f, to an arm, pL, uponthe back shaft p3.

l prefer, also, to put the extra pol-ishin g pressure upon the spools by fixing a piece to the cam px, to come in contact with an adjustingscrew in the lever pv, and to resist its motion during the last two layers. This piece upon the cam will pass clear ofthe adjusting-screw in the lever when the cam-shaft d6 begins to turn. The tension of the thread as itis wound upon the spool is regulated by passing between pinching-surfaces, before referred to. These are formed by two hard-steel faces, a4, one fixed (so as vto be easily replaced) to the boss part a5 of the thread-guide, the other to the end ot' an arm, a9, jointed to projections from Ithe boss, as shown in Figs. 9 and 10.

The end of the arm a9 carries an adjustingscrew, at", the point of which acts against the end of a spring, a", fixed to the boss a5, as shown. (See Fig. 9.) By means of this screw and thespringnV the pinching action, and thus the tension upon the thread, is regulated.

The canlq for feeding the einptyspool is fixed on the shaft d6. It acts upon an arm, q', ixed'upon the shaft q2, which passes from end to end of the operating part of the machine. Upon this shaft an arm, qa, is secured for each head in a vertical position, to which another arm is bolted, the end of which is formed into a V-trough,q4. The attendant places the empty spools one in each ot' these troughs while the machine is winding, vand when the empty spool is to be passed onto the spindle the V- trough is moved by the cam q till the axis of the spool comes opposite the spindle k2, when the hollow part l* pushes the spool from the trough g4 onto thespindle k2, and then the V-trough assumesthe first position by the action of the cam q. l

)Vixen the spools are filled with thread and the winding stops the rst operation of the chan ging cams is to lift the thread-guides from the spools, and when this movement begins a linger, m4, secured to one, m, of the three-sliding rods, traverses across and catches the thread between the thread-guide and the spool, so as to take it to one side; but before this is accomplished au arm, T5, carrying a knife and spring-point, is caused by a cam, t", to descend upon the edge of the,spool. The knife cuts an incision into the edge of the spool and then lifts, the same movement ot' the cam causing the spring-point to press against the spool, and this point fixes a limit to the unwinding of'the vthread at a' point in a line with the incision cut by the knife. `About this .time the I thread, which has been brought to one side by the finger m4, is caught by alhoolr, s, which pulls it tirmly into the incision, and by the time this is accomplished the hooi; has brought that part of the thread between itself and the spool against a knife-edge on one side of the hook, which severs the thread on that side, and the thread'on the other side of the hook has-"become pinched between it and a spring.

The spindle k2 is then-withdrawn, and the full spool falls against a pin, t, iixed in the sideof the bracketv A', which tilts it over the rod m,

so that it rolls down `the spout into the trough z, in front of the machine, and while an empty spool is being put upon the spindle the thread (bythe tension upon it) takes such a line be- I tween the thread-guide and the pinching apparatus that it is caught between the'hoop or shoulder of the spindle k2 and the endof the Ispool. This holds the end of the thread secure. The hook s then ascends and releases the end of the thread, and the thread-guides are lowered upon the spools,when the change is completed.' Then the traverse-rod f5 is` adjusted and the winding begins.

The cani 1" for actuating the incision knife and point is fixed on the shaft d6., It acts-upon will assume such aline `al1 arm, r', iixed on a shaft, r2, passing from end to end of the operating part of the machine. Upon vthis shaft there is a verticalV arm', r3, for each head, t0 which a rod, r4, is jointed, having a screw-couplin g for adjusting its length. This rod r1 is also `jointed to. one arm of a bell-cranked lever, T5, having its fulcrum upon a stand, r6, from the bracket A. Toone arm of this lever the incision-knife r" is attached, as shown in Figs. 9 and 10, and also a spring, r, bent at the end and sharpened to a point. This springLpoint rs descends below the edge of lthe knife ri and comes tirstv in contact with the spool. It is madeelastic, so that it can remain in contact after the knit'e has been lifted to allow thethread to enter the incision.

The. cam. s,.for working the hook, is fixed upon the shaft d4. It acts upon a lever, s', free to oscillate upon theshaft r2, and this lever is connected bya rod, s2, with an arm, s3, upon a shaft, s4, passing in hearings on the brackets A' from end to endot' the operating parts of' the machine. Upon. this shaft s4 an ar |n,s5, is fixed for each head, which has a slot on its Aend that tits'a pin tixed in the end ot' the hook s. This hookis made to slidefreelyin a groove formed in a bracket, 89, and close to oneside of the hook a knifeedge .'s", is fixed by a set.- screw,s", (see Figs. 9 and 10,) and upon the other side a spring, s, is arranged to press against the side of the hook, keepin g it against the knife-edgeupon its'other side.' It will now be seen that when the hook catches the thread and pulls it downward one side will come be.

tween the spring and hook and the other side against the knife-edge, and that, the thread' between the threadguide a7 and hook as to pass close against the spindle, so as to be caught between the shoulder o t a collar upon the spindlel andthe end of the spool, where it is held secure.

The forms of the 'cams and-their times ot' action in relation to each other will now be described by reference to the diagramson Fi gs. Sand 4. lu these diagrams the formfot' each cam is represented upon a straight line, supposed to be divided into three hundred and sixty degrees, so that the point marked 0 and 360 repre'- sent the same pointofthepath ot'tliecam whenv the two ends ot' the lines'vare joined together to form a circle. The diagrams show the times at which the cams act relatively to eachother 'by being drawn with an assumed zero of each can. upon the same vertical line, so that the movements and times f action at any point of the revolution otl the camfshat't vwill'be seen at a glance by drawing a vertical linethrough the given pointnpon the diagrams. Fig'. 3 will explain those cams upon the belt-changing cam-,shaft c, which makes one revolution for 'each set ot' spoolsflled with thread-.that is,

onefsndden semifrotation when the winding' is completed land vthe other when .thechange or" the spools is effected. rlhe cams. stand atl the zero-point 0 in respect to the bowls acted upon when the machine is winding. b* repgree, and remains in sents the brake-lever -cam for stopping the windin The brake is fully applied by the time the cam has passed through' forty-six degrees ot' rotation, and it remains applied during the remainder ot' thel one hundred and eight;Y degrees of the first semi-rotation, and at the'one hundred and ninety-third degree the brake is fully withdrawn, and remains so for the remainder ofthe second semi-rotation. The cam ZX for the brake d?, acting to sto'p the motion of the spool-changing cams dfand dix, is withdrawn'from the pulley d during the first semirotation and is applied d uriug the second semirotation. The cam px, for lifting the threadguides when actuated h v a cam upont-he beltchanging cam-'shaft c3, lifts the-guides between .the ninetie'th andone-hundred and eightieth degree ot' rotation and lowers them during` the remaining three hundred and sixty degrees ot' rotation, 'or duri-ng theseco'nd semi-rotation.

The lwlt-changing cam e2 acts. to traverse the belt from the winding-pulley b to the spool changing pulley (l during the iirst semirota -tion and back again during the second semirotat-ion.

Fig. 4 is the diagram ot' the clams upon' the spoolfchan ging cam-shafts d6 and. d6". These cams are at the assumed zero (0) in relation to the bowls acted uponwhen the machine. is winding, and they make one continuous rotation after the tirst and .before the secondsemi-v rotation otthe helt-changing cam-shaft e3.

' 'When the thread-guides are operated upon by a. cannp", on the shai't di", as is now preferred, they are lifted from the spools during. the 'first twenty-live degrees of rot-atioinremain up-till the three hundred and twentyeighth degree, and `from this point descend to the three hundred and tit'rv-t'th degree,` then remain down during the remainder of' the three hundred. and sixt 'degrees otrotation. The-incision and point cam r causes the knife to reinainstatiomngv during the iirst thirteen degrees, to eut the incision between the thirteenth and thirty-seventh degree, to remain in the incision. .between the thirty-seventh and sixtythird degree, to withdraw from the 'incision between the sixty-third and eightieth degree,

and then remain stationary to the ninety-second degrer-,and tinallyassninetheiirst position, withdrawing the point between the ninety-second and one .hundred and seventh degree, remainingstationaryduringthe renniinder ofthe rotation ot' the cam.

l 4The cam malfor actuating the tin gers "m4, that take 'the thread to one side, produces no move ment till the twentieth degree ot' rotation. It then begins to act, and has made the mo\e ment.` to'push the thread to one side, so as to he caught h v the hook s atthe sixty-third dethis position tillthennetvth'ird'degree, when it begins to retire to its trst p'ositiom'which it attains at.. the one hundred and tblty-Iit'th degree, `then renn'iining stationary the remainder ot the three hundred aud-sixty degrees ot' rotation. working the hook s produces no movement till The can] s for' the tenth degrceof rotation, when. the-hook begins to ascend to catch the thread,this movement being finished at the titty-fifth degree, from which point the hook remains stationary till the sixty-fifth degree, when it begins to desce`nd to its lowest point, which it attains at the one hundred and tenth degree. Thethread being now cut, one end being held by the spring sa, the hook remains in this position to the three huudred'and th irty;eighth degree, then makes the shortascendin g movement to release the end oi' the thread, and remains in this position during the remainder of the three hundred and sixty degrees ot' rotation.

The cam 13 for actuating the hollow spindle 1.4 produces no movement during the first one hundred and thirty-six degrees ot' rot-ation, when it begins to withdraw to give space for the full spool to be discharged. The short movement is completed at the one hundred and fortieth degree. The spindle then stands till the one hundred and ei ght-y-second degree, at which point it begins to withdraw still farther, ending this movement at the two hundred and thirty-eighth degree, when it lremains stationary to the two hundred and severity-second degree to allow the empty spool to be brought opposite the spindle; then it begins its back movement, forcing the empty spool out of the feeding trough or cradle qd' onto the spindlejvz, this movement being completed at the three hundred and twenty-eighth degree, the hollow spindle remaining in this .position during the remainder of the three hundred and sixty 'de-v 'grecs of rotation.

The canile8 for giving 4end motion tothe spindle lczforrotating the-spools produces 'no motion during the first one hundred and forty vdegrees ot' rotation, when the spindle begins to.

withdraw from the fullv spool, and finishes this movement at the one hundred and ninety-tit'th degree, when it becomes stationary, and remaine so till the two hundred and fifteenth degree, at which point it begins its back movemen1'.,'ending it at the two hundred and seventieth degree, and remaining stationary during the remainder ofthe three hundred and sixty degrees ot' rotation. y

The cam q for bringing the empty spool oppositethe spindle 7a2 is formed so that the trough i Aor cradle gt'is stationary during the lirst two hundred and twenty-eightdegrees ot' rotation. '1t then begins to move;the trough so as to bringwthe empty spool opposite the spindle, which, it accomplishesat the three hundred and titty-sixth degree otrotation, when the 'trough becomes ,stationary till the three hundred and secondfilegree 'of rotation, at which point the trough begins to go'back to its position when the machine is winding, at which, point'itarrivesl at thethree hundred and thirtysecond degree, bein g'stationary'd uri ng the remainderot' the three hundred and sixty de-A grees of rotation.y Y

' 1 have now particularly descrihedthe nature ofmy invention and the manner oi' carrying the same into effect, and would remark thatI amaware that machines have been proposed having several heads, all worked together at the same time, and in such machines the distribution of the thread was intended to be effected by self-acting means; but in such machines the stopping of' the winding when the spools were full by a brake, the securing of the end of the thread to full spools, the removing and replacing ot' them by empty ones. thel arranging of the threads to wind onto the empty spools, and vthe starting of the machine to wind were not performed by self -acting means, as by my invention hereinbet'ore described. l therefore wishvit to be understood that I do not confine myself to the details herein given so long as the peculiar features of my improvementlare retained; but
